So milileter
mili means 1000
1 leter=1000milileters
3liters=3000milileters
so
how many 200's fit into 3000
200 times what=3000
divide both sides by 200
what=15
answer is 15 of such cups can be filled
The answer to this question would be the first box (left hand side). Hope that helps :)
Answer:
nah it's easy to get rid of sadness just think of why you were happy than think of who or what makes you happy
Answer:
C
Step-by-step explanation:
Everything else can be simplified to 2/5, except for 9/20
<span>let number of hours of Isaac,Ruby and Svetlana worked be x,y and z respectively.
so y= x+6 ( equation 1)
note: Ruby (y) worked 6 hours more than Isaac (x)
z = 4 x y ( equation 2)
note : Svetlana (z) worked 4 times as many hours as Ruby (y)
x+y+z= 126 ( equation 3)
note: Together they (x,y,z) worked 126 hours.
substitute eqn 1 to eqn 3
so x+y+z= 126 becomes
y-6 + y+z-126
2y+z= 126+6
2y+z=132 (equation 4)
the substitute eqn 2 in eqn 4
so 2y+z=132 becomes
2y+4y=132
6y=132
y=132/6= 22
so y=22
substitute y value in equation 1
so y= x+6 becomes
x+6=22 and
x= 22-6 = 16
and substitute x and y values in equation 3
so 16+22+z= 126
38+z= 126
z= 126 -38 = 88
So the number of hours Isaac worked (x) is 16 hours
number of hours Ruby worked (y) is 22 hours
number of hours Svetlana worked (z) is 88 hours</span>
